Add generic DbRepository for raw SQL execution

Introduced DbRepository<TDbContext> to provide basic database operations, including methods for executing raw SQL commands via ExecuteSqlRaw and ExecuteSqlInterpolated. The class exposes the underlying DbContext for use in derived classes. Existing DbRepository<TDbContext, TEntity> remains unchanged.
